] Hiring the right people is extremely crucial to Fog Creek
] Software. In our field, there are three types of people.
] At one end of the scale, there are the unwashed masses,
] lacking even the most basic skills for this job. They are
] easy to ferret out and eliminate, often just by reviewing
] a resume and asking two or three quick questions. At the
] other extreme, are the brilliant superstars who write
] lisp compilers for fun, in a weekend, in Assembler for
] the Palm Pilot. And in the middle, you have a large
] number of "maybes" who seem like they might just be able
] to contribute something. The trick is telling the
] difference between the superstars and the maybes, because
] at Fog Creek Software we only hire the superstars.

This is great and is exactly what I look for when hiring candidates!
